How to clean a clog on an Ultimaker nozzle

[hponda 0]

Hello Everyone,

 

I have run into a problem with the Ultimaker S5 Bundle Pro. I had queued up list of print jobs of different colors. After completing the one print job, the printer started another print job. After starting the printing, the material was not able to stick to the build plate and it started printing everything on the nozzle and after sometime stopped printing. Soon as I checked the printer, I immediately removed the print job floating on the nozzle. I performed Hot and cold pull on both the print cores. But when I opened the print head, I saw bad clog there on the nozzle and It has stuck around the nozzle and I cannot find a way to remove. Can anyone please help me?

The best way to remove it is to manually heat the nozzle, start the temp low so the filament is firm on outside but pliable on the heater block. This helps it pull off cleaner. then using some long nose pliers pull the bulk of the filament off. You can then heat it more so it's liquid then wipe it with a rag.

Thank you so much for the suggestion.

 

I followed below steps if anyone run into the same problem:

 

Go to Preferences → Maintenance → Print head → Print core cleaning

 

After this, I didn't follow any further steps of core cleaning instead I just let the nozzle heat up. Once the nozzle heated, I wrapped a cloth on a screw-driver and wiped all the melted filament and properly cleaned the nozzle. And, that's it! 

 

I was actually looking for a separate maintenance option for heating up the nozzle but I didn't know that we can heat-up the nozzle by simply following the core-cleaning steps.

It's not a maintenance option, but if you press the printer icon on the screens side menu to view the printcores and filamnet, you can press on the printcore you wish to heat up and then in the top right click on the 3 dot menu icon and you can set temperature.

I see, I didn't notice that particular option in the 3D Printer Maintenance menus but I will check and see if I can find it.

 

Thank you!🙂
